DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saw pod of the type having a long toothed blade and further having a handle at one end of the blade. Inserts a saw blade into a long hard body that defines a recess that can keep the saw teeth out of contact with the surroundings, and a pod on the carrying part of the worker's clothing, such as a belt. Equipment for direct or indirect attachment.

2. Description of the Related Art Among craftsmen, a kind of hand saw called a pruning saw is used not only for professional gardening but also for professional pruning of growing plants such as vineyards and large orchards. The accessibility of the saw is very important to the actual work situation of the worker, especially when carrying the saw by means other than by hand and still having the ability to carry the saw when needed for work. is there. One difficulty for workers is that they use many plant tools during their work, such as plant shears, pruning instruments, blades, or means for treating bark wounds. It is a must. When climbing the ladder, leave both hands free,
It would be extremely important to keep hands free by carrying a saw that is not used immediately. Shortly thereafter, the saw must be taken out and held in the hand for sawing work. This has to be done with even less effort and little movement, as the user may adopt a complex position between tree branches where the space available for sawing and arm movement is limited. No.

One of the above types of pods is described in Japanese Patent No. 7
It is known from 328959. This pod is based on a conventional pod with an upper opening, in which the saw blade is inserted and subsequently the saw blade must be moved axially with respect to the entire length until it reaches the bottom of the pod. Conversely, when the saw is removed, it must be completely pulled axially from the sheath. Therefore, this type of pod is not well suited for the use situations described above.

[0004] The use of tooth protectors formed in a partially open configuration has been known for some time from Swedish patent SE113470. This shape cannot actually be used as a sheath. One reason for this is that the pocket for receiving the tip of the saw blade is relatively long, requiring that the tip of the blade be inserted axially into the pocket, and that angular mobility is not possible.
Yet another reason is that the tooth protector must be connected to the saw handle by a leather strap, which must be tied and attached in place. It is against the object of the present invention to have a string that must be tied or untied when the saw is inserted into or removed from the contoured object. In addition, Swedish Patent SE113470 does not include any means for attachment to a user's clothing.

[0005]

The present invention aims at overcoming the disadvantages of the cited pod and making a more suitable pod. One object of the present invention is to make a sheath that is simple in construction and easy to carry by the user and allows the saw to be quickly and easily removed when needed and that the saw can be easily reinserted after use. That is. Another object is to make a sheath that can be securely attached to a portion of the worker's clothing, such as a belt, and can be easily removed from a portion of the worker's clothing when desired. It is a further object of the present invention to make a pod that does not collect dirt or moisture and that is visually pleasing and durable at the same time. It is a further object of the present invention to make a saw and a sheath that allows the blade to be inserted without the blade coming into contact with clothing.

[0006]

According to the invention, at least the main object is achieved by the features disclosed in the characterizing part of claim 1. Preferred embodiments are further described in the dependent claims.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, a sheath body is indicated by reference numeral 1. This sheath can preferably be coupled as shown in FIG. 3 with a separate hanger 2 which can be detachably attached to the belt 3 as shown in FIGS. FIGS. 4 and 5 further comprise an elongated saw blade 5 having a plurality of teeth 6, indicated by the reference numeral 4, and a gripping portion 8 and a fastening portion 9 into which the saw blade is inserted. It shows that it is made to receive a hand saw with the handle 7. More specifically, the saw blade has two screw members 1
At 0, it is attached to the fastening portion 9 of the handle. The grip portion 8 of the handle has the base shape of the pistol handle, and is relatively large but acute angle with the extension straight line of the tooth of the saw blade.
It forms an angle of 40 to 55 °.

Referring to FIG. 1 to FIG. 3, these figures are:
The sheath is shown as being formed as an elongated hard body and having a groove 11 opening along a major portion of the body length. This groove has a bottom 12 and two side walls 13, 1
3 '(contrast FIG. 6). Along the end of the groove, ie the lower part, these side walls extend close to each other, and in the rear or upper part, they are widened to make room for the saw handle 7. In this upper part, the side walls are taller than in the lower part.
The side walls and the bottom end both terminate in a transverse wall 14, from which two flanges 15, 15 'extend parallel to each other without a continuation of the bottom.

At the distal or lower end of the sheath 1 there is provided a short cover 16 with an open mouth, which is preferably made continuously with the lower side walls 13 and 13 '. ing. The purpose of the cover 16 is to receive the free end or tip of the saw blade 5,
Serves as a releasable holder for the free end of the saw blade 5. The cover 16 is preferably made with a through hole 17 through which dirt and moisture can naturally exit from the inside of the cover. At the lowermost end of the sheath 1 is a tubular portion 18 having a transverse cavity 19, which, if desired, allows the lower portion of the sheath to be tied to the user's leg. Transverse cavity 1
A strap or leather strap can be attached through 9.

The second element for releasable retention of the saw is a spring rest that resiliently holds the saw handle to the pod body. The spring hook has two projecting members 20, 20 '.
(See FIG. 6), and the projecting members 20, 20 '
It protrudes inward from the side wall of the sheath body and can bite into the two recesses 21 and 21 'of the saw handle. These depressions are formed by making one screw 10 for connecting the blade 5 to the retaining part 9 of the handle clearly shorter than the transverse hole in which the screw is provided. This creates enough space between the end of the screw and the mouth of the transverse hole to allow both projecting members 20, 20 'to be pressed in. Press-fitting of the protruding members can be realized by the inherent elasticity of the side walls 13, 13 'of the sheath. However, for reasons of manufacturability, it is appropriate to make a suitable sheath or body from a polymer material having low elasticity. Next, preferably, the two projecting members 2
The 0,20 'is provided on another elastic part, which is basically shaped like a U-shaped clamp 23, in particular on an extension 24 which is folded inside the clamp. In order to be able to return to the same shape even after a large deformation, the U-clamp may be made from a polymer material having a large elastic deformation and a range of shape memory. One suitable material is polyoxymethylene. Hollow 2
The protrusions 20, 20 'are preferably tapered to facilitate the entry of the protrusion members 20, 20' into the 1, 21 '. As shown in FIG. 2, the U-shaped clamp 23 can be made independently, but slides axially along the pod body 1 from the starting position to a position where it contacts the transverse wall 14 and the side wall 13 , 13 'are permanently attached to the pod body 1 by sliding past the locking means 25 inside the high part of the 13'. The locking means 25 ensures that the U-clamp is locked in the desired position when the U-clamp contacts the transverse wall 14.

On the lower side wall of the lower part of the sheath 1,
An opening 26 can be made through which the inserted saw teeth can be seen from the outside. Connecting means 27, 27 'for connecting the sheath body 1 to the hanging member 2 are provided outside the flanges 15, 15', and the hanging member 2 is connected to the belt 3 as shown in FIGS.
Attached to This hanger 2 is made as a spring clip with a U-shaped hook 28, the hook 28
And can be securely held.

In one preferred embodiment of the present invention,
The connecting means 27, 27 'are part of the connector shown later in FIGS. 8 to 11 and allow the sheath 1 to freely pivot with respect to the hanger 2 during use, which is furthermore desirable. If it can be removed. Hanging equipment 2
The lower part comprises a first flat element 29, at the lower end of which the first flat element 29 is connected to a second flat element 30 which is smaller than the first flat element 29. The first flat element 29 has a keyhole-shaped through-hole 31 formed therein. This hole preferably has a round and wide first portion 32 and an elongated and narrow second portion 3.
And 3. In practice, the first rounded portion 32 will have a diameter 1.5 to 2 times the width of the second portion 33 of the elongated hole. Inside the second flat element 30 there is provided a projecting member 34 facing the lower part of the second part 33 of the elongated narrow hole. In practice, the projecting member 34 can be made as a cylindrical shaft made continuously with the second flat element 30.

The connecting means 27 is generally horseshoe-shaped and has an inner neck 35 extending straight from the flanges 15, 15 ', with a collar or thickened portion 36 at the outer end of the neck 35. The neck 35 and the collar 36 have a common side opening 37, which in the application described above is perpendicular to the axis of the sheath. The outer diameter of the collar 36 is slightly smaller than the inner diameter of the round hole portion 32, but is significantly larger than the width of the elongated narrow hole second portion 33. The diameter of the neck 35 is slightly smaller than the width of the second portion 33 of the narrow hole.

The use of the connecting means is clear from FIGS. When the pods are connected to the hangers 2, the two are oriented at right angles and the connecting means 27 are inserted into the wide round first portion 32 of the through hole 31, as shown by the arrow in FIG. In the next step shown in FIG. 10, the connecting means 27 is moved down to the narrow second portion 33 of the through-hole 31, where the connecting means 27 surrounds the protruding member 34 inside the disk-shaped element 30. In the last step of FIG. 11, the pod is rotated 90 degrees to the position where it is freely suspended. In this state, the pod can pivot with respect to the hanging member 2, but since the protruding member 34 is surrounded by the connecting means 27 and prevents vertical movement between the pod and the hanging member 2, the pod is simultaneously suspended. It is securely attached to the tool 2.

In order to remove the pods from the hanger 2, the pods must first be rotated relative to the hanger 2 to a 90 degree orientation. Next, the connecting means 27 is moved upward to the wide first portion 32 of the hole 31 and laterally moved out of the hole 31. As shown in FIGS. 7 and 8, the opening 37 opens in the same direction as the open groove 11 of the sheath 1. The pod 1 is carried vertically from the worker's waist with the opened part in front. The fact that both the connecting means 27 and the groove 11 are open forward reduces the risk of the sheath 1 being unintentionally detached from the hanger 2. The sheath 1 can only be removed at one particular position rotated 90 degrees backward from the vertical position in FIG. The possibility of accidentally bringing the pod 1 to this position during actual work is negligible. Only by intentional rotation of the sheath 1 to the horizontal rearward position can the user remove or connect the sheath.

Referring to FIGS. 12 and 13, one alternative preferred embodiment of the present invention is shown. This alternative embodiment differs from the sheath shown in the other figures in that the side walls of the sheath have side projecting flanges 38, 38 '. The purpose of the protruding flanges 38, 38 'is to keep the grooves and saw blades far away from the operator's legs and clothing. Referring to FIG. 13, the cross section of the groove is wider near the opening, which makes it easier to insert the saw blade.

FIG. 4 shows that the free end of the saw 4 is
6 shows the sheath 1 with the saw 4 inside, with the protruding members 20, 20 'inserted into the recesses 21, 21' outside the handle 7; In this state, the grip portion 8 of the handle 7 extends between the upper flanges 15, 15 'of the sheath 1 and faces obliquely upward and rearward. Therefore, the grip portion 8 can easily approach the hand.

When the saw 4 is released from the sheath 1, the handle 7 is grasped and protruded from the upper part of the sheath 1,
A slight force is sufficient to deflect the resilient wall portions away from the recesses 21, 21 'to move the protruding members 20, 20'. Next, the saw 4 is pivoted outward, as shown in FIG. 5, and the tip of the saw 4 can be removed from the cover 16 with a short pulling movement.

When re-inserting the saw 4 into the sheath 1, the opposite procedure is used, the tip of the saw being first inserted into the cover 16 and then the handle being pushed between the side walls of the upper part of the sheath. The protruding members 20, 20 '
Is moved to the depressions 21 and 21 ′ of the handle 7. One fundamental advantage is that it does not provide the axial movement that would have been required if the saw had been inserted into a tubular sheath,
A simple action, such as rotation in a tangent plane, is that the saw can be removed from the pod according to the invention.
For the operator, this means that the saw can be removed with a small, easy movement without requiring a large space for the arms. Another advantage is that the pods of the present invention allow free swinging relative to a hanger attached to a belt, rather than being permanently connected. With the connector described in FIGS. 8-11, the sheath can be easily removed from the hanger whenever desired. There is one connecting means 27, 27 'on each of the flanges 15, 15'. This allows the choice of hanging pods on the left or right side of the waist.

The invention is not limited to the embodiment shown in the figures. It is possible to replace the resilient projecting member holding the cover or handle recess for the saw tip with another known element for releasably holding the saw tip or handle. One or more magnets may be used for this purpose. Similarly, it is not necessary to attach the pods to the belt hanger. It would also be possible to attach the pods to the clothes with glue or burrs. This further allows the sheath to be attached to the lower leg of the operator if desired.
